Wondering just how quite our rifles are with subsonic ammo and a suppressor?
The vids really are tough to judge. Sound quality osnt the best for gunfire.
Anyway just wondering????

Quiet and I don't think they are unless you use subsonic and a suppressor. It might be possible to shoot indoors without ear protection. But will the action completely cycle?
 
I had a sparrow supressor and used it on a 10/22, a Savage bolt action and a 22/45 pistol.
Sub sonic ammo will NOT cycle a semi auto, but is VERY quiet. You would manually cycle the semi auto,s
The Savage bolt action with the CCI quiet ammo and the supressor in place made about the same noise as a Daisey Red Ryder BB gun.
All ammo is sub sonic in a pistol, but generaly the pistol is louder than the rifle,s.
 
Some subsonic will cycle it just fine. Other, like the CCI Quiet, will not cycle it. The Gemtech Silencer ammo works nice in my SBR. Took a video of the first mag I ran through it, only one issue and it was a FTF. The 4.5" barrel makes the sound similar to a handgun...just different noise from the action.

Subsonic 22LR through Spectre II and 4.5" SBR - YouTube


Can't tell much difference in regular and subsonic ammo with that barrel length, but you would on a standard barrel.

Sub-sonic ammo will cycle the 15-22. Agulia standard velocity, CCI sub-sonic, standard velocity and the Walmart black-box cycle with and without a silencer.

With a silencer, all I could hear was the riffle cycling and the bullet hitting the target with a YMH Mite. With super-sonic ammo, indoors it makes little difference and not hearing safe, outside, the firing is silent but the sonic crack is less pronounced and seemed hearing safe from the rifle. A friend who was observing outside said it sounded different and came from a different angle with the silencer on.
 
Armscor SV also cycles without a silencer. Haven't found more since after I received the silencer.
 
Seems a bit conflicting.

With the full length 15-22 barrel (and suppressor), will either

a) CCI Std Velocity
and/or
b) CCI Quiet

Reliably cycle in a 15-22?

As it should. The noise is not at the muzzle with the suppressor. It's just the sonic crack following the projectile down range.

Same result when hunting with suppressed full power rifles. If you miss, or are shooting at one animal in a group, you'll often have the remaining targets run directly toward you. That's because they don't hear anything from the muzzle...they hear the sonic crack as it goes past them and bounces off the trees, etc. They'll run away from the sound, which is often right at the shooter.

Same advantage in when the prey is human. It's not silent, but the other guy doesn't really know where it's coming from. That's the main reason (along with flash suppression) that is used to answer the "why would you try to suppress a supersonic round" question.

ETA: yeah, that was answering a question not really asked...but thought maybe some readers didn't know some of the reasoning

A) shouldn't have any problems
B) you probably have a single-shot rifle

I've never bought any of the Quiet, so that answer is based on what I've seen others report.

Thanks, I've been collecting the Std as it becomes available and I've been trying to get a box of CCI quiet. Plenty of time until my F4 is approved before testing though :(
 
Yeah, I had seen that before, but I was wondering with a full length barrel and the additional back-pressure created by the suppressor if it was sufficient enough for the 15-22
 
At 300fps slower yes the cci could have trouble cycling the action. I understand that.
But most subsonic ammo is 1050ish. Plus with the added back pressure, the bolt should cycle.
The question Im asking is just how quite is it? Seems to me some people say its as loud as a BB gun. Others say its the same volume just no sonic crack.
So which is it?

All I shoot in my 15-22 is subsonic ammo and I have many thousands of rounds thru it. I mainly shoot CCI SV & Norma Tac-22 but have tried other brands too. All cycle the action just fine & my bolt always locks back on the last round. I recently shortened my barrel to 4.5" and so far ( a few hundred rounds) I have had no new issues.

I use the 22Sparrow suppressor and from what I understand, a suppressor helps with these low velocity rounds by increasing back pressure. I can't think of any reason why I would use CCI Quiet.

When shooting my 15-22 suppressed, it is very quiet but not silent. Loudest component is the action cycling... something you don't hear when shooting without a suppressor. If you want to see how quiet 22LR can be when shot suppressed, put the suppressor on a bolt gun. By doing so, you obviously don't have much noise from the action. I say not much because believe it or not, you can actually hear the springs in the action working. Now that gun is quiet & best way to describe it would be like shooting a pellet gun.

I will state don't jump into suppressed shooting without giving it a lot of thought. By doing so, you will shoot more... a lot more. You will have more shooting buddies too. Then you will start reading stories about SBRs ( short barrel rifle) and end up submitting another form & getting your 16" barrel cut down. For some folks it stops there, but then I started thinking that if I converted my 5.56 AR to 300 Blackout, then I could also shoot 30 caliber subsonic rounds suppressed on my home range. So that caused me to purchase a new suppressor (Saker 7.62) and a new 300 Blackout upper with 9" barrel... and of course 2 new forms.

I admit I am addicted. However being able to shoot on my home range without bothering the wife, the farm animals & the neighbors... well that is priceless.
 
Im in the same boat. I have two houses both around 350yds away. However I shoot towards a valley, 90 degs away from them. Just want to be a good neighbor.

Quiet enough that I don't need hearing protection & it doesn't bother my horses in the least. My wife & neighbors don't even know I'm shooting. The suppressor knocks down the vast majority of the noise coming from the detonation of the powder in the subsonic round. That can be demonstrated, as I said above, by shooting a bolt gun. I use a CZ 455. However a semi-auto makes a bit of noise whenever the bolt is cycled. Pull back your charging handle & let go. That metal to metal sound is what you will mainly hear, along with the sound of the bullet's impact.

Subsonic ammo is quieter... period. The less bang... the less noise to be suppressed. Then of course you don't get the sonic crack, which is surprisingly loud. When I intro folks to shooting suppressed, I always start shooting with the suppressor on. Then to give context, I remove it & shoot a few rounds. The difference is mind blowing. Then you can give a physics lesson by putting the suppressor back on but loading the first few rounds with high velocity ammo. That is when you learn how loud that bullet gets when it breaks the sound barrier.
 
15-22 16" HV, standard vel & CCI quiet, rem subsonic cycled the gun without can but require hearing protection.
15-22 16" Tested with 4 different 22 lr cans all cycled the gun no hearing protection needed
15-22 10" with 6" integral suppressor ( Innovative Arms)- Fed HV 36gr bulk, cycled the action and no hearing protection indoors or outside.
So a 16" is quieter with quiet/subs without can, 16" with SV or subs with can is more quiet ( no real difference in sound between the SV and subs) and the quietest ( movie quiet ) IA integral with hv. I tried some (5 rd) of SV and it did not cycle. The IA is only a suppressor, not an SBR, so you do not need ATF permission to travel to a legal state. The only thing you hear with the IA is the action. I have been looking at ways to quiet the action. Check out there video, all you here is clicking. Be Safe,
